I suddenly felt nautious followed by vomiting. symptoms of stomach flu. and after i feel like something is in my chest. could this anxiety or?

I can't diagnose you: Gastroenteritis symptoms may include: diarrhea, nausea, vomiting, abdominal cramps/pain, headaches, muscular aches ; pains as well as fever (low grade). Bloody stools are not usually associated with gastroenteritis. Do you feel overwhelming anxiety when you experience the nausea ; vomiting. If these are new ; acute symptoms would suspect a stomach flu before trying to blame it on anxiety.
